GUY L. WOODJARD, OF SAN DIEGO, CALIFORNIA.

To all whom t may concern? Be it known that LGUY L. WooDJARD, a

citizen ofv the United States, residingat San Diego, in the county of Diego and lState of California, have invented certain newA` improvements. over my application for' spring Oilers, filed in the IUnited States Patent` Office January f5, 1916, SerialNo.` 70,-v

387, and the objects of rsaid improvements are: First, to provide a device of this class which v`increases the oil reservoir space;

second, to provide a device of this class in" which the oil hole cover is simpler, `more elicient and not so liable to get out of order; third, to provide a device of this class which is more simple of construction, durable, and

. efficient; fourth, to provide a device of this vice. Fig. 3 is an end view thereof. Fig. 4

class which allows relief for the oil centrally at the sides so that it flows more freely at the ymiddle of bothlsid'es than at other portions of the device; and foifth, to provide means for Aclosing the ends of the ding to its durability.` p t v With hese and other objects in View as will appear hereinafter, my invention consists ofcertainu novel features of construction, combination and arrangement of parts as will be hereinafter described in detail and particularly kset forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon which form a part of the specification, in which:

Figure 1 is a perspective view ofthe preferred form of the device shown mounted on a spring ready for use. Fig. 2 is a top or plan view of the. preferred form of the deis a longitudinal sectional view thereof. Fig. 5 is a bottom view thereof.

The casing "pad'Qpoil holeA y*cover 3, and:` shield 4 constitute the principal parts of my' l 'n oiler.- .pp

The casing l consists of a rectangularly shaped piece, preferably metallic, provided with downwardly extending right-angle edges; These portions 1b are adapted to, fit into the usual slight grooves between the two upper spring leaves and hold the 'device in position on-theupper spring leaf. The main) portion is provided at each end with downwardly extending ridges lc formed integrally in the metal.

flanges la, which are provided with inwardly, extended portions Y lb along n theirl lower It vis also provided with a .4 "raised portion 1d' which increases 4the .capac ity of the oil reservoirrand may be rectang- -ularly shaped as `shown iny Figs. Zand ,8, or

diamond shaped as shownin Figs. 6 and 7 as desired,as `itis obvious` that different shapes inayfbe pressed into the top of this` 4metallic case for increasing the capacity of the reservoir and for allowingfreer seepage of the oil'in the 'middle on each side than at other portions. In this raised portion l, is provided ani oil hole le against the under surface of `which is secured a spring bladek f 3 some distance from said hole, so thatl the loose end byreason of the inherent spring of the' material will close the hole 1e but may be pressed down for admitting oil through. ysaid hole but will prevent dirt from enterthe Ioil reservoir through the hole 1? louiited on the lower surface of the main portion 1 and between the two flanges 1a is a pad'preferably of felt provided with a central hole 2a of suitable size to contain a sufficient quantity of oil. This pad 2 is suciently compressed to make a tight fit between the upper surface of the upper spring leaf and the lower surface of the main portion of the casing 1 but'will allow the oil to seep `out gradually along the sides and run down between the leaves of the spring when the springs are in operation. rlhe ridges 1c will cause the ends to be considerably tighter and prevent seepage out through the ends. ln the modified form of construction shown 4in Fig. 6 of the drawing the enlarged porcation. I do not wish to be lilnited to this particular construction and to the modificationsl therein shown and described. but desire to include in the purview of my invention the construction combination and arrangement substantially as set forth in the appended claims, as it is obvious that slight modifications may be made in the form without deviating from the invention..4 y

It is obvious that with this construction there is provided an oiler for springs which will allow the oil to seep down between the leaves of the spring when said springs are vin operation` that by particular shapes in the enlarged portion of the casing relief is given to the pad so that the oil will have freer movement near the middle of the casing on each side than in other portions, that the ridges l. provide means for increasing pressure on the pad at the ends for preventing leakage at the ends, that the shield 4 provides means for closing the ends so that the pad is covered and completely incased thus adding to its durability.

Having thus described my invention what- I claim as new and desire to secure by Letters VPatent, is:

Copies ot this patent may be obtained for ve cents each, by. addressing the construction with-slight modithe upper leaf of a spring,

1. In a spring oiler, thecombination of a casing provided with side members adapted itt it overthel ,upper leaf of thespring, with integral ridges in each end thereof, and with an integral raised portion on the upper sur; face thereof, and a resilient pad provided with acentral hole for an oil retainer.

2. In a spring oiler, the combination of a casing provided with side members adapted to it over the upper leaves lof the-spring with integral downwardly extending ridges in each endV thereof and with an upwardly extending portion on the upper surface thereof provided with an oil hole therein, means secured therein for covering said oil hole and a resilient pad provided with a central hole for an oil reservoir.

3.In a device of the class described,the combination of a casing adapted to t over provided with a raised portion on the upper surface. thereof for increasing the oil capacity vand a felt pad provided With a central hole therein mounted between the top portion of said casing and the upper surface of said spring.

4. In adevice of the class described, the v combination of a casing adapted to fit over the upper leaf of a spring provided With a raised portion on the upper surface thereofv for increasingthe oil capacity and means mounted in said casing for forming an oil ,reservoir between said casing and the upper spring leaf.

In testimony whereof, I have hereunto set my hand at San Diego, California this 24th day of `January 1916. v
